class /*iterator*/ |  | (since C++23) (exposition only*)

The return type of `chunk_by_view::begin`, and of `chunk_by_view::end` when the underlying view `V` is a `common_range`.

### Member types

Member type | Definition
`value_type` | ranges::subrange<ranges::iterator_t<V>>
`difference_type` | ranges::range_difference_t<V>
`iterator_category` | std::input_iterator_tag
`iterator_concept` | std::bidirectional_iterator_tag, if `V` models `bidirectional_range`, otherwise std::forward_iterator_tag.

### Data members

Member name | Definition
`parent_` (private) | A pointer to the parent `chunk_by_view`. (exposition-only member object*)
`current_` (private) | ranges::iterator_t<V>, an iterator to the begin of current chunk. (exposition-only member object*)
`next_` (private) | ranges::iterator_t<V>, an iterator to the begin of next chunk, if present. (exposition-only member object*)

### Member functions

(constructor) | constructs an iterator (public member function)
operator* | accesses the element (public member function)
operator++operator++(int)operator--operator--(int) | advances or decrements the underlying iterators (public member function)

### Non-member functions

operator== (C++23) | compares the underlying iterators (function)
